/* The sign-in page.
 *
 * It is the first thing anyone at BAAC sees, and it used to be the one screen
 * that did not belong to the system: its own brown (#4b2d16, matching neither
 * the sidebar nor the token that claimed to define it), its own borders, its
 * own 6px corners against the system's 8 and 14, and a form floating loose on
 * the background while every other screen puts its content in a card.
 *
 * So there are no colours written in this file. Every value comes from the
 * tokens in app.css, which means the dark panel here and the sidebar behind it
 * are the same paint -- and stay the same paint if the company brown is ever
 * changed, because there is only one place to change it.
 *
 * Logical properties throughout: this page is used in Arabic more than in
 * English, and it must mirror without a second stylesheet.
